Abstract
Highly effective polarizers are described having a degree of polarization P of at least 95% and a dichroic ratio Q E
= quotient of the extinction in the blocking position to the extinction in the transmitting position, of 10 or more over almost the whole wavelength range of visible light between 400 and 800 nm, the said polarizers comprising polymer products containing polyacetylene, in whose matrix 70 to 90% of all comonomer units are vinyl alcohol units. The polarizers are used in the form of films with a stretch ratio (see fig. I) (1 = length after stretching, l o = length before stretching) of more than 300%. They can be produced by polymerization of acetylene in the solution of a copolymer in which 70 to 90% of all comonomer units are vinyl alcohol units, in the presence of a nickel catalyst.
